The pole pieces or body I are magnetized by permanent magnets 8 mounted by suitable bolts 2| and 22 on opposite sides of the body 1.

The entire unit is covered by a non-magnetic casing 23, preferably integrally mounted over said magnets and body.

The cleaning and removal of trapped particles from the magnetized passage is accomplished easily by pushing a. non-magnetic spatula through said passage 6 so as to push the particles to the outer fringes of the passage from where the particles can be lifted manually or by suitable nonmagnetic tweezers or pliers.

The device is of a unitary character, integrally united parts of which have their exposed surfaces suitably finished to form smooth, sanitary passages without cracks, thereby positively preventing bacterial accumulation.

I claim:

1. For use with a sausage stufling device, a tubular conduit comprising two spaced sections, a magnetic body interconnected therebetween to form a third conduit section, said magnetic body having a longitudinal passage permitting passage of sausage mix through said sections.

2. For use with a sausage stuffing device, a tubular conduit comprising two spaced sections, a magnetic body interconnected therebetween to form a third conduit section, said magnetic body having a longitudinal passage permitting passage of sausage mix through said sections, said spaced sections being non-magnetic.

3. For use with a sausage stufling device, a tubular conduit comprising two spaced sections, a magnetic body interconnected therebetween to form a third conduit sections, said magnetic body having a longitudinal passage permitting passage of sausage mix through said sections, a permanent magnet on said magnetic body and a non-magnetic covering around said magnet an said body.

4. For use with a sausage stumng device, a tubular conduit comprising two spaced sections, a magnetic body interconnected therebetween to form a third conduit section, said magnetic body having a longitudinal passage permitting passage of sausage mix through said sections, said longitudinal passage being in the form of a slit.

narrower than the width of said conduit in said spaced sections.

5. For use with a sausage stufiing device, a tubular conduit comprising two spaced sections, a magnetic body interconnected therebetween to form a third conduit section, said magnetic body having a longitudinal passage permitting passage of sausage mix through said sections, said longitudinal passage being in the form of a slit narrower than the width of said conduit in said spaced sections and an enlarged outlet chamber formed in said magnetic body between said slit and one of said sections.

6. For use with a sausage stufiing device, a tubular conduit comprising two spaced sections,

a magnetic body interconnected therebetween to form a third conduit section, said magnetic body having a longitudinal passage permitting passage of sausage mix through said sections, said longitudinal passage being in the form of a slit narrower than the width of said conduit in said spaced sections and an enlarged outlet chamber formed in said magnetic body between said slit and one of said sections, and a shoulder formed along each side of said slit in said outlet chamber forming a pocket to collect'magnetic particles swept through said slit.

7. For use with a sausage stufiing device, a tubular conduit comprising two spaced sections, a magnetic body interconnected therebetween to form a third conduit section, said magnetic body having a longitudinal passage permitting passage of sausage mix through said sections, said longitudinal passage being in the form of a slit narrower than the width of said conduit in said spaced sections and an enlarged outlet chamber formed in said magnetic body between said slit and one of said sections, and a shoulder formed along each side of said slit in said outlet chamber forming a pocket to collect magnetic particles swept through said slit, said outlet, chamber diverging toward the adjacent section.

8. For use wiht a sausage stufllng device, a tubular conduit comprising two spaced sections, a magnetic body interconnected therebetween to form a third conduit section, said magnetic body having a longitudinal passage permitting passage of sausage mix through said sections, said longitudinal passage being in the form of a slit narrower than the width of said conduit in said spaced sections and an enlarged outlet chamber formed in said magnetic body between said slit and one of said sections, and a shoulder formed along each side of said slit in said outlet chamber forming a pocketto collect magnetic particles swept through said slit, and an intake chamber in said magnetic body convergin from the other section to said slit.
